DEMOTS4995J: 1.2W @ 8Ω, 2.2 ~ 5.5 Vin

Summary

The TS4995 is fully differential structure power audio amplifier which is capable of delivering 1.2W of continuous RMS output power into an 8Ω load at 5V. Due to its differential inputs, it exhibits outstanding noise immunity.

An external standby mode control reduces the supply current to less than 10nA. A STBY MODE pin allows the standby to be active High or Low. An internal thermal shutdown protection is also provided, making the device capable of sustaining short-circuits.

The TS4995 features an internal fixed gain at 6dB which reduces the number of external components on the application board, and the flip-chip package with 9 bumps allows maximum space saving.
